Spiritual Openness, Revisiting a Potentially Important Aspect of Spirituality: Scale Review and Revision.

Religiousness and spirituality (R/S) exert important influences on individuals across a range of domains. Spiritual Openness is theoretically linked with the personality trait of Openness to Experience, suggesting promise for future research. Using responses from 366 undergraduates on the Spiritual Experience Index-Revised (SEI-R: subscales of Spiritual Openness and Spiritual Support), analyses evaluated and revised the SEI-R, deleting poor items and generating a 10-item measure. The new SEI-S exhibits better psychometric properties and reduced participant burden, and subscales displayed a curvilinear relationship in which increases in Spiritual Openness showed a trade-off in levels of Spiritual Support.
